Fel Iron is a metal that can be mined. Fel Iron ore can be smelted into Fel Iron bars. Two ore are required in order to smelt one bar. It is found in rocky regions, as well as those heavily populated by demons. This is because Fel Iron is likely a corrupted version of the Iron found in Kalimdor and Eastern Kingdoms. Apart from being found in Outland, it can also be mined on the Isle of Quel'Danas, along with all the other Outland ores.
It is believed that Fel Iron is a corrupted variant of Draenor's .
